| crystallization and preliminary x-ray data of the fada adhesin from fusobacterium nucleatum. | fusobacterium nucleatum is a gram-negative anaerobe prevalent in the oral cavity that is associated with periodontal disease, preterm birth and infections in other parts of the human body. the bacteria attach to and invade epithelial and endothelial cells in the gum tissue and elsewhere via a 13.7 kda adhesin protein fada (fusobacterium adhesin a). fada exists in two forms: the intact form (pre-fada), consisting of 129 amino acids, and the mature form (mfada), which lacks an 18-residue signal se ... | 2006 | 17142900 |
| efficient gene transfer and targeted mutagenesis in fusobacterium nucleatum. | fusobacterium nucleatum is a gram-negative anaerobe important in dental biofilm ecology and infectious diseases with significant societal impact. the lack of efficient genetic systems has hampered molecular analyses in this microorganism. we previously reported construction of a shuttle plasmid, phs17, using the native fusobacterial plasmid pfn1 and an erythromycin resistance cassette. however, the host range of phs17 was restricted to f. nucleatum, atcc 10953, and the transformation efficiency ... | 2006 | 16115683 |

| analysis of the incubation period for measles in the epidemic in greenland in 1951 using a variance components model. | this paper presents a model for analysing the incubation period of highly infectious diseases in populations where almost all susceptibles become infected during an epidemic. the model leads to a simple method for estimating the variance of the duration of the incubation period without any distributional assumptions. further, the influence of covariates on the duration of the incubation period can be analysed. data from the epidemic of measles in greenland in 1951 are analysed and it is found th ... | 2006 | 1594801 |
| somatic reversion/suppression in duchenne muscular dystrophy (dmd): evidence supporting a frame-restoring mechanism in rare dystrophin-positive fibers. | many duchenne muscular dystrophy (dmd) patients are known to have rare staining dystrophin-positive fibers, termed "revertants." the precise etiology of these rare fibers is unknown. the most likely explanation, however, is somatic mosaicism or somatic reversion/suppression. immunocytochemistry was performed on serial sections from deleted and nondeleted patients, with a panel of antibodies--9219, 1377, 9218, and dys-2--that span dystrophin. both familial and nonfamilial patients possessed rever ... | 2006 | 1570844 |

| the educational process at the mount sinai school of medicine: the first 25 years. | although the charter for the school of medicine was signed in 1963, and active recruitment of faculty commenced almost immediately, the recruitment of students, in fact, did not begin until several years later, with admission of a first-year and a third-year class in september 1968. from that time to the present, the class size has increased from a small, carefully selected group of 36 first-year students to its current size of 115 students in each of the basic science years and 132 students in ... | 2006 | 2685587 |
